Abstract (en)

[origin: EP2557449A1] A polarizing-axis control plate 180 includes a first polarization area 181, a second polarization area 182 and a polarizing-axis control plate area shading part 183 arranged at a boundary between the first polarization area 181 and the second polarization area 182 and also arranged in a position corresponding to an image generating area shading part 163 to shade all or part of right-eye image light and left-eye image light. When the right-eye image light and the left-eye image light enter the first polarization area 181 and the second polarization area 182 respectively, the polarizing-axis control plate 180 emits the incident image light and the incident left-eye image light in the form of linearly-polarized lights whose polarizing axes intersect with each other at right angles or circularly-polarized lights whose polarizing axes are rotated in opposite directions. An image generating unit 160 includes the image generating area shading part 163 arranged at a boundary between a first modulated-light generating area and a second modulated-light generating area to shade incident light. The polarizing-axis control plate area shading part 183 is formed so as to contain a plurality of straight lines each having a width narrower than a linewidth of the image generating area shading part 163.
